ST. LOUIS (AP) - Aaron Boone is set to rejoin the Houston Astros on Friday, about five months after undergoing open-heart surgery, and will be activated when rosters expand on Sept. 1.
Boone has been playing in the minor leagues since Aug. 10, going 3 for 15 with one RBI for Double-A Corpus Christi before moving to Triple-A Round Rock where he was 0 for 4 in two games.
Astros manager Cecil Cooper said Cooper is healthy, but his timing is off.
Cooper said he hadn't thought about how Boone would be used the final month.
The 36-year-old Boone had an operation in late March because of a congenital defect in his aortic valve. He signed with the Astros in the offseason.
